Particle Board Plant
Manufacture of good quality plywood requires defect free wood. At present in India, about 80% timber for plywood comes from short rotation trees of plantation origin. Conversion ratio from such timber is low and higher grade plywood is difficult to be made from such timbers.
Particle board is an alternative panel to plywood. Manufacture of particle board can be done with any type of wood and other lignocellulose material and conversion ratio is higher than plywood.
Particle board industry in India does not have a strong foundation parallel to plywood due to lack of technical know-how, indigenous machinery and partly due to customers reluctance to accept the product.
Establishment of Pilot Plant for Particle board at IPIRTI will serve many purposes:
1. The plant is set up with entirely indigenous machinery which will encourage the industry to set up bigger plant with indigenous machinery.
2. Exploration of the suitability of various timber species, soft and hard for particle board manufacture.
3. Development of suitable adhesive with low formaldehyde content and standardize process parameters.
4. HRD through training for supporting the industry.
5. R & D for product development
Formaldehyde Emission Test Chamber
To evaluate the steady level of formaldehyde emission a 1 m3 formaldehyde emission chamber has been fabricated as per the specification of EN 717-1 and ISO/DIS 12460- 1 and installed at IPIRTI. Volatile organic compounds and formaldehyde for the sample drawn from building materials and interiors can be measured in this chamber. This chamber method determines the formaldehyde emission at steady state from wood based panels under defined conditions relating to average conditions in real life. This method is also applied to estimate the formaldehyde concentrations under various conditions in practice by the use of mathematical models.
Testing of particle board and plywood's of 1 m2 surface area as per EN 717 and ISO/DIS 12460-1 will be carried out and the report will be issued as per the international requirements. No National Standard has so far been formulated to safeguard the interest of users of wood based panels. It is therefore, utmost necessary to standardize the manufacturing process and test method to determine the optimum level of formaldehyde emission in the finished products and formulate national standards.
Peeling lathe for processing plantation timbers
As large number of plywood industries in the country is utilizing plantation timber species for production of plywood, the new facility will simulate factory conditions. It also helped in creating a pilot plant scale production line of 1.2 m x 1.2 m size plywood.
A new facility was added for carrying out R & D and training activities in the Institute by the installation and commissioning of 1.2 m size peeling lathe.
Ultra filtration equipment
A new pilot plant facility consist of three Column having three different size ceramic membrane consist of two stainless steel (SS) tank, of 40 liters capacity has been recently established at IPIRTI. These three vertical membranes are connected with feed pump (3HP).
This equipment is meant to fractionate chemicals in mixture into definite molecular fractions by passing through micro-sieve of ceramic column. Using this equipment various molecular mixture present in waste black liquor will be fractionated into various molecular weight range and the same were used for manufacture of adhesive for wood based panel products.
Microscope with software analysis system
The microscope having Trinocular observation tube with UIS2 (Universal Infinity System) optical system, objective optical magnification 4x to 100x oil immersion along with 10x eye piece magnification has been installed at IPIRTI, Bangalore. This microscope is attached with ProgRes® capture Pro 2.6 camera with image analysis software to measure the cell structure like length, width, diameter and other features. It is useful to identify the wood samples and to study their anatomical characteristics.
In addition to this we can study the physical characteristics of the insects.
